.IltIxT AND UNEQ TQUZL' 1 m r tio r moan To all whom 112.111; concern:

Be it known that l, Goa? ()Bnran, a citizen of the United States. resident-of Louisville, the county of il elierson and State of entiucky, ha- 1- e made a certainnew and usefnl invention in Means for Sounding; i tlarin-G-ones{and declare the following: to he a toll; clean and exact. dctaription ot the same such as will chat. others skilled in the art to which it appertains to make and use the invention, reterence' being; had to the acconnianying draw" and to letters or figures of reference marked tin-neon, which "form a part. o't' this speciti :ation.

Fig. 2 is a yertieat transverse sectio'n, on the line 2-2 igli the plan limit of 3 is a view similar to Fig. 1 with parts broken away, the section liming taken on the line 5 3, Fig. '22- npon the opposite side ot the rack.

The invention relates to means or riiiging the alarm gongs ot street will? or other vehicles, having for its ohfi'o'ir to provide an improved device tor the purpose oi giving; a clear sound in the stroke of t he clapper and :1 continuity of st 'okes with a minimum of etlort on the part at the nintoruian or driver.

The invention c nsists in the novel construction and icomhinations of parts as hereinattcr set forth.

ln the acconuianying drawings, illustrating the inventicn the lcttcrn, designates the gong or hell and 1). is the rotary apper. of straight character, having journal hear hugs centrally of its length at r, upon a shaft 1?, supported at its free ends in arms 0, 0, extending downward from the tloor ot the car. This clai iper has atthe free end ot each arm thereof a recess f, of cylindrical character, forming the receptacle for a loose ball lunting movement therein, the halls being continedin place by inward extending rims 1 at the extremities of the arms.

it the side of the clapper upon the shaft d, a pinion 7-1, is provided, having pivoted to its inner taco anarenate pawl Z, having; an intnrned l'lOLi end Z", capable of" engage 3:3 3 GHARLEE; TEL LQUKSVILLE,

mont with a ratchet wheel m. forming" a central part: of the clapper. lal ovcment otthe pawl away from its ratchet when 'tlisengaged therefrom is limited by a pin a, carried by said pinion and capable of engagement with a stop arm. Z of the pawl to stop the same in its moven'ient. i

For the purpose of o 'ierating the pinion and rotating the clapper a sectoriorin rack 0, has pivotal hearings 0, upon a shaft p, connectin the arms e, c, at the upper portions thereof, said rack having an anvil face 7', at, its upper portion extcndin to one side of its pivot and adapted to he struck by a plunger 5', extending through a perforation s in the floor of the car and operated lav the foot of theinotorman or driver. u

in the operation of the invention, the

plunger works powerfully upon the rack to strike the same to one side, at the smile time pawl 7 has normal engagement with the ratchet wheel m, through force of gravity, as shown in Fig. 3 oi"? the drawings, and at the end otthe stroke. of the rack released from such engagement, also tl'irmigh'forcc of gravity, as shown in "Fig. 4 of the drawings. The sector rack is returned to normal position by means of a coil spring 1;, having connection with a lug t, at the upper portion of the ark, this lug having stop engagement with the vertical face it, of the casting u, 1

of which one of the arms (3, is made an integral part, when the ra Gk has been turned about forty-five degrees", the upward or re turn movement of the track being limited by engagement oi its anvil face 1 with the lower face of the castilw- Having thus described my invention, what I claim as new ant-l desire to secure by Letters Patent is 1. In an alarm, a stationary gong, a stationary shaft, a rotary striker loosely mounted on said shaft and having two oppositely extending arms provided each with a short end r'ecesg-a loose ball in each recess,

" a ratchet Wheel fast to said striker, a pinretraction spring or .sai

v ion loosely mounted on said shaft, and a piva shaft havingnsupport in said downwardextending arm below one edge of said lower face, avibratory rack upon said shaft pro vided with an upper anvil face and an end lug, a plunger for operating said rack, a retraction spring for said rack, a lower shaft having support in said downward extending arm, a rotary clapper loosely mounted on said lower shaft, a ratchet wheel in rigid connection with said clapper, a pinion upon said lower shaft in engagement with said rack, a pawl pivoted to said pinion, capable of intermittent engagement with and release,

from said ratchet wheel through forceof gravity, the upper anvil face of said rack having stop engagen'ient with the lower face of said casting at the end ofits return stroke and sand lug'havlng. stop engagement with the end wall of said casting at the end of the effective stroke.

In testimony whereof I affix my signature,
